Product Overview
The MP70FS microcomputer control blow molding machine places every critical function under one central controller. Sequencing, heating, parison profiles, and clamping logic are coordinated digitally, giving plastic chemical drum producers a repeatable process with very little operator guesswork.
Because the system stores forty mould recipes, switching between drum sizes is quick, and the double proportional valve keeps hydraulic pressure and flow precise under changing loads.
Key Features
- Centralized Microcomputer Control: A single controller runs sequencing, temperatures, and parison programming, replacing scattered manual adjustment with one reliable process.
- Forty Mould Recipe Memory: Stored settings let operators change drum moulds in minutes instead of re-tuning the machine from scratch.
- Double Proportional Valve (PQ): Electro-hydraulic pressure and flow control keeps clamping and carriage motion smooth and repeatable.
- Heavy-Duty Clamping for Drums: 150 kN of clamping force and a 500 x 360 mm platen hold large chemical drum moulds firmly and without deflection.
- Uniform Drum Wall Thickness: Parison wall control keeps drum walls even, so every container meets strength and weight targets.
- Zero-Flash Parting Control: An in-cylinder hydraulic lock removes flashes and improves the sealing surface quality of chemical drums.
- Fail-Safe Safety Interlock: Category-4 safety door guarding with dual limit sensors stops clamping power instantly when a guard opens.

Plastic chemical drums for acids, alkalis, solvents, and intermediates rely on even walls and sound sealing, which the microcomputer control system supports through repeatable parison settings.
The machine also covers agrochemical, lubricant, and industrial detergent containers that must resist chemicals and survive stacking and transport.
Product Q&A
Q: What does centralized microcomputer control mean?
A: One controller manages the entire sequence, including heating, hydraulic motion, and parison programming, so the process stays repeatable and few manual adjustments are needed.
Q: How many recipes can be stored?
A: The system holds forty mould recipes, so operators can switch drum sizes and restart production quickly.
Q: Is the machine suitable for chemical drums?
A: Yes. Even wall thickness, a locked clamping circuit, and reliable sealing make it well suited to chemical and agrochemical containers.
Q: How is hydraulic precision achieved?
A: A double proportional valve controls both pressure and flow electro-hydraulically, keeping clamping and carriage movement consistent.
